Explanation:

1. The recommended sleep for 12 - 18 year - olds is 8 - 10 hours. This is based on general health guidelines as this age group needs sufficient rest for growth and development.
2. The deepest sleep according to the circadian rhythm typically occurs in the early morning hours, usually between 2 - 4 am. The body's internal clock regulates sleep - wake cycles and promotes deeper sleep during this period.
3. When asleep, the body repairs tissues, consolidates memories, regulates hormones, and lowers body temperature. These processes are essential for physical and mental well - being.
4. The stages of the sleep cycle are non - rapid eye movement (NREM) stages 1, 2, 3, and rapid eye movement (REM) sleep. NREM stages are characterized by different levels of brain wave activity and muscle relaxation, while REM sleep is associated with dreaming and rapid eye movements.
5. During REM sleep, the eyes move rapidly, brain activity increases, and vivid dreams occur. Muscles are temporarily paralyzed to prevent acting out dreams.
6. Three ways to improve sleep are maintaining a regular sleep schedule, creating a comfortable sleep environment (dark, quiet, cool), and reducing screen time before bed.
7. Melatonin is a hormone produced by the pineal gland that regulates the sleep - wake cycle. It can help with sleep by signaling to the body that it's time to sleep, and may be used as a supplement to treat sleep disorders or jet lag.
8. A sleep log can help track sleep patterns, identify factors that may be affecting sleep (such as caffeine intake or stress), and monitor the effectiveness of changes made to improve sleep.
9. Sleep deprivation is the condition of not getting enough sleep. It can be acute (short - term) or chronic (long - term).
10. Sleep deprivation can be caused by factors such as stress, poor sleep habits, medical conditions (e.g., sleep apnea), medications, and environmental factors (e.g., noise or light).
11. Three effects of not sleeping enough are fatigue, impaired cognitive function (e.g., difficulty concentrating, memory problems), and mood changes (e.g., irritability, anxiety).

Answer:

1. 8 - 10 hours
2. Between 2 - 4 am
3. Tissue repair, memory consolidation, hormone regulation, body temperature lowering
4. NREM stages 1, 2, 3, and REM sleep
5. Rapid eye movements, increased brain activity, vivid dreams, muscle paralysis
6. Regular sleep schedule, comfortable sleep environment, reduced screen time before bed
7. A hormone produced by the pineal gland that regulates the sleep - wake cycle; can signal it's time to sleep and be used as a supplement for sleep issues
8. Track sleep patterns, identify sleep - affecting factors, monitor sleep improvement effectiveness
9. The condition of not getting enough sleep
10. Stress, poor sleep habits, medical conditions, medications, environmental factors
11. Fatigue, impaired cognitive function, mood changes
